A quadrupedal Spinosaurus with a hump instead of a sail.There are some things in the skeleton that support this ideas..The hand would be turned sideways, like in anteaters, since theropods had their hands facing each other and large claws look cool that way and would be less problematic.

Not quite. It has been -disputed- but it's still the most current posture theory. Worst case scenario it would get -tired- of walking on it's nuckles, lest it has its brain inside it's wrists I'm pretty sure it would not-kill- itself. Probably it needn't a lot of walking at all, and spent most of it's time with most of it's body in water or just laid on the shore.

Shoulder blades dont point at the neck at all and other large dinosaurs do not have that problem either. There might be some "evolution-lag" with the wrist not being as properly developed as in other large quadrupeds, but thats about it, nothing wrong with the arms or shoulders.

Nope, this thing definitely wasn't a quadruped and most palaeontologists would agree.

Yes but none of those other dinosaurs are theropods.

And there are other reasons:-the knuckles do not touch the ground the right way for it to walk.-the shoulders do not move in a way that allows this thing to walk on its knuckles.-The arms are unable to bear its weight.-the centre of balance was farther back than on other theropods making quadrupedal locomotion unnecessary.

Not disproven: rather, cast into doubt. While it was argued against, it seems fairly likely Spinosaurus did have abnormally small hind legs after all, and in the absence of much unambiguous forelimb material it's hard to say for certain right now.

This is actually the second specimen to preserve the short legs--Stromer found another partial skeleton, known as "Spinosaurus B". Sadly it was destroyed in WWII like the original remains, and later researchers considered it an indeterminate theropod, possibly the same thing as Sigilmassasaurus. Based on the new Spinosaurus specimen, though, we can tell that the original specimen, Spinosaurus B, and Sigilmassasaurus fossils are all different parts of the same species.

Perhaps. Though it does beg to wonder why such an extreme physical shift from Suchomimus to Spinosaurus. And honestly, why was there a biological need for a "whale" dinosaur? I agree with Spino being the bear of the Saurian world, but to the extent of evolving to be nearly 100 percent water adapted doesn't make sense with creatures in that niche already existing in the first place.

Honestly we should have expected it from the 1940's onward. If you look at the drawing of the original Spinosaurus fossil in Germany, it's depicted with short hind limbs. It's still pictured with the incorrect skull and upright stance (vertical), but it's been there all along. Nobody seems to have ever looked at the old drawings- which they should have. The German specimen had complete legs IIRC and no Spinosaurus fossil until now had complete legs. Rather, they were based off Suchomimus.

mmmh, makes a lot of sense, after all Spinosaurus lived in Egypt(desert environment) and was a fish eater, fishes are naturally rich in fat so the hump would work for storing said fat, working like a mix between a heron, a camel and a grizzly bear.

this actually make sence because most animal who have long head need to support that weight and the stuff we know about the spinosaur now the tail seems like its not to help support the weight if we look at the fossil of a tyrannosaur the tail is the right length to support it head another thing I remember another creature that uses a massive sail and they were guadrupedal.

I'm sorry, but I have to disagree with this theory. It's interesting, but I don't see why a Theropod should be quadruped.

Based on their hipbones, I think they seem better being bipedal. Not only that, they'd have an easier time catching terrestrial prey. Besides, the arms seem too weak to be able to support the front half of the body. Let alone run.

I have to say I've been a big fan of your work ever since I found you on DA, I love the way you not only mutate creatures, but you give them such a rich and whimsical background that they no longer are just flat pieces of art. Every detail is planned out and offers such a rich variety to the creatures from your imagination. You are definitely an inspiration for me as I have such a great time creating strange and wacky beasts of my own.I always drift back to your page when I have a blank moment, and really I just wanted to say thank you for being an inspiration. Please keep up the wonderful work .
